Second Quarter 2010 Results

REIT Taxable Earnings and CORE Earnings

Estimated REIT taxable earnings for the three-months ended June 30, 2010, were approximately $979,000 of which $921,622 was paid out as dividends on July 29, 2010 to the 2,304,054 shares of common stock outstanding for stockholders of record on June 3, 2010 ($0.40 per share as of June 3, 2010). The estimated REIT taxable earnings represents an annualized taxable return on March 31, 2010 equity of 18.3%. The amount paid out as dividends represents an annualized return on March 31, 2010 equity of 17.2%. The Company distributes dividends based on its estimate of taxable earnings per common share, not GAAP (generally accepted accounting principles) earnings. REIT taxable earnings and GAAP earnings will differ primarily because the non-taxable unrealized changes in the value of the Company's interest rate hedges are included in GAAP earnings whereas, because they are not realized, hedge valuation changes are not included in taxable earnings.

Core earnings for the quarter ended June 30, 2010, were $973,482. Core earnings annualized return on equity was 18.2% based on March 31, 2010 equity. "Core earnings" represents a non-GAAP measure and is defined as net income (loss) excluding impairment losses, gains or losses on sales of securities and early termination of interest rate hedges, unrealized gains or losses on interest rate hedges, and certain non-recurring expenses. CORE earnings may differ from GAAP earnings as GAAP earnings include the unrealized change in the value of the Company's interest rate hedging program and in Q2 2010 certain non-recurring, non-taxable, expenses. ARMOUR was fully invested as of July 22, 2010 after completing the deployment of its June 2010 equity capital raise.

GAAP Earnings

During the quarter ended June 30, 2010, the Company lost approximately ($700,000). The Company reported a non-realized change in the value of interest rate hedges of ($1,456,525), which along with certain non-recurring, non-taxable expense items, accounts for the difference between the approximately $979,000 of REIT taxable earnings and GAAP earnings.

Regulation G Reconciliation

REIT taxable income is calculated according to the requirements of the Internal Revenue Code rather than GAAP. For the year ending December 31, 2010, ARMOUR plans to distribute at least 90% of its REIT taxable income in order to maintain its tax qualification as a REIT. The following table reconciles ARMOUR's consolidated results from operations to REIT taxable income for the three months ended June 30, 2010:

ARMOUR believes that the foregoing reconciliation of REIT taxable income is useful to investors because REIT taxable income is directly related to the amount of dividends the Company is required to distribute in order to maintain its REIT tax qualification status. However, because REIT taxable income is an incomplete measure of the Company's financial performance and involves differences from net income computed in accordance with GAAP, REIT taxable income should be considered as supplementary to, and not as a substitute for, ARMOUR's net income computed in accordance with GAAP as a measure of the Company's financial performance.
